Hi everyone! Anyone knows good virtual spaces to discuss #computergraphics , especially in videogames? I have some doubts about blood and gore #vfx but I don't know where can I learn more.

💡 A nice bonus of the latest Blender 5.1.1 sub minor version update is that it now supports Vulkan on my ThinkPad laptop with integrated Intel UHD 620 graphics... and maybe yours too ✌😄

FYI - The latest Intel Graphics Driver for the 8th Gen chipset in my laptop was released back in Dec 2025 - 31.0.101.2140 with Vulkan 1.3.215 support.

Cem Yuksel, one of the most creative researchers in the #computergraphics field, warns about the danger to travel to #Malasya to the #SiggraphAsia2026 conference for #LGTBIQA people.

A country with really stupid but dangerous anti-gay laws as well a hostile social environment for people in the collective.

Watch what he proposes. And do what he says, it will cost you nothing.

For the first time in over 10 years (with just a Covid break), I won’t got to #siggraph this year. I don't think this is the right time to travel to the U.S. And there will be many others who don't want to or can't travel there either. Unfortunately, #acm decided it was best to cancel the virtual tickets this year. So I guess it'll be a SIGGRAPH without me. I'm looking forward to the next SIGGRAPH in #Vancouver. Or anywhere else outside the U.S. #usa #trump #computergraphics #science

I met Andrew Glassner at #SIGGRAPH back in the early 1990s, when I was still a #ComputerGraphics academic researcher. I remember him as a superb communicator. His recent book is a non-#CG one: "Deep Learning: A Visual Approach" (2021). This book contains no equations at all, only simple diagrams and illustrations. A tour de force of visual communication, that. Go, CG!

I like #AI as a computation tool but, as my friends on MathsTodon know, I genuinely detest the common way #DL is now being taught to #ComputerScience and #DataScience undies—no maths, just API call-fest. Consequently, new CS and DS grads entering #IT—who are fashioning themselves as "#AI experts", either due to profit motive or through sheer ignorance—lack the adequate mathematical and intuitive understanding of this rather "deep" subject. Andrew's new book will not remedy their maths shortcoming, of course, but it surely will give them a thorough, intuitive grasp of DL, IT's current "darling of the day".

Indeed, this book is so gentle that I dare say 8th graders could be taught DL, out of it. That is my ardent endorsement of this book.

Armed with this intuition, those youngsters with adequate background in undergraduate maths could move up to books like "#DeepLearning", Goodfellow (2016) and "Pattern Recognition and #MachineLearning", Bishop (2006).

When matsuoka-601 dropped his WebGPU fluid simulation demos, they left everyone in awe—pushing the limits of what's possible in the browser with breathtaking realism and incredible performance. 💦

Now, he's been kind enough to take us behind the scenes, breaking down the magic behind the mesmerizing waves, high-performance physics, and real-time rendering!

A tiny way to compute a square / triangle wave at the same time without conditionals, only basic arithmetic and shifts.

This can be used for #oscillators or animations etc. #algorithm is a variant of HAKMEM 149.

Can also be used to draw a square. (And other shapes, see previous toot)

Code also shows how to draw a diamond shape by rotating the square by 45°.

There are two versions, optimized for size and optimized for speed.

Cutting/clipping with vtk 9.4.0 *sigh* sure it's only a low-resolution data-set, but it looks horrible with this vertex-based coloring... it's going to be some work to patch this to make it use proper interpolation using a fragment-shader based approach #OpenGL #vtk #dataViz #computerGraphics

After more than 15 years i am stepping into the world of vtk again... 9.4.0 to be precise, which was just released about two weeks ago. Let's see what changed, what remained the same and what was added. #computerGraphics #vtk #OpenGL

My old graphics card started to show its age after about 8 years (especially in the more demanding/modern games) and it was time to make an upgrade to a new beast: PowerColor Hellhound Radeon RX 7900 GRE. It's doing great, even at 4K resolution and I love how quiet and cool it is running even while gaming and using the OC mode. About time the PC takes back some of that gaming time from the Steam Deck :)

The rings tower high over the midnight horizon with Saturn's shadow cast over them. A bit of artwork I made for @badastro last week.

This image combines Cassini imagery of Titan, Enceladus, and the Rings with a NASA star map, and a picture of overcast clouds I took from and airplane a few years ago. The rings were rerendered for the atmospheric perspective and the shadow.
